I see that I may have misinterpreted the question. While there are relatively few main anti-cancer drugs, in my experience I was quite overwhelmed by the very large number of different drugs I was offered to help deal with the various side effects of treatment. These were for pain, inflammation, nausea, skin burn etc., and included a gradual increase in potency (and side effects) from T3 through liquid morphine to Fentanyl (patch), the steroids, and anti-nausea medicines.

Each of these has potential side effects, and when you start to combine them, I think it's very difficult to know what's causing what. Some people sail through. Some don't. I sailed through 80% of my treatment, and then went very sideways.

Also, be aware of the potential for late-onset side effects. I didn't have any trouble with the Cisplatin initially (meaning no nerve damage, but the stuff *is* poison, basically) and was "signed off" by my medical Oncologist, but months later had some significant concerns about my hearing and "numb feet", both signs of peripheral neuropathy, or nerve damage likely caused by the Cisplatin, and I was not told this was possible. This has, however, gradually healed and I'm for the most part not concerned now. If it happens with your father, take heart that it will probably resolve in time. Any sign of hearing loss or ringing in the ears needs to be immediately discussed with the medical onclogist before any other doses are given. This will not resolve itself, it is permanent.

Good luck, and stay strong.
